“…the Board of Directors at its meeting held on February 20, 2017 appointed V Ramakrishnan as the Chief Financial Officer of the company with effect from February 21, 2017,” the Mumbai-headquartered company said in a BSE filing.

Ramakrishnan, or Ramki as he is popularly known, joined TCS Finance in 1999, and served as the Finance Head of TCS North America for seven years.
